Which risk increases when an FSK modulated signal encounters multipath interference?

💡 Explanation

Multipath interference creates delayed and scaled replicas of the signal; because Frequency Shift Keying (FSK) relies on distinct frequencies to represent symbols, overlapping signals cause inter-symbol interference, undermining discrimination. Therefore, error rate increases, rather than improved range because of signal boosting.
